摘　　要：提出了在立体模型下利用立体象对的象基线测量水平航片相对航高的方法，并建立了相关的计算公式：Ｈ＝Δｈ×ｂ／Δｂ，式中，Ｈ为水平航片的相对航高；Δｈ立体象对象主点的高差；ｂ为水平航片的象基线；Δｂ为立体象对象基线之差。A new method was suggested for measuring the relative flight height of the level airphoto using the image base line of the stereopairs under stereo model. The equation relevant was instituted as H =Δ h×b /Δ b , here, H was the relative flight height of the level airphoto, Δ h was the height difference between stereopair photograph centers, b was the image base line of the level airphoto, Δ b was the difference of the two image base lines.
